Did you "Bounce To Clips" after stretching?
 
I've had similar popping issues after an edit or adjusting Audio Snap and and bouncing the track helped.
 
Good luck!

I get this very rarely.. not sure what I am doing when it happens but I am usually moving fast when it does... I have an UAD and Apollo audio interface(s).
 
I can still save before quickly exiting and am using X3C... I am sure this started happening a few versions earlier.  The only worry I have is that if I was monitoring when it happens, my monitors will blow.

Ok, something is majorly wrong with Sonar now - I started a new project with only MicroTonic and Diva running and out of nowhere I got an nddll.dll error and Sonar crashed.  Now Sonar crashes upon starting every time, even with projects that were completely stable just days ago.
 
I am going to reinstall my MOTU drivers and if that doesn't work, Sonar.  This is frustrating!

Oh boy, I cannot uninstall my MOTU driver or install a new MOTU driver overtop!  I'm really at a loss here.

Ok, I wasn't able to uninstall the MOTU driver, however I was able to reinstall an older version of the driver from August and now I am able to load previously stable projects.
 
The new project I started tonight, which has Microtonic and Diva in MIDI tracks only crashes Sonar upon start-up!  I guess one of them needs to be reinstalled.  I'll try that next.

Ok, Diva seems to have been the culprit - it had a BETA notice which I see from the website was a bug.  I have installed the newest version and it seems to be working, my new project hasn't crashed since, but its only been about 5 minutes.

I don't know if the problem with DIVA is related to the pop problem I was having before, but it could have been the MOTU driver or the time stretching I was doing.  I hope I don't see this problem again.

Hello, i am using sonar platinum and often get these loud pops . It happens to me when i am looping. If i am listiening to a repeating sequence, particularily with a heavier project, i get a loud pop as the loop ends. I too am wortied about blowing a speaker. I am using a motu 16a. Any ideas?
Thanks

Not sure how to prevent it but to protect yourself and your system, insert a limiter on whatever bus your loops preview through.

Hello and thanks, I doubt that will help, but I will surely try. I notice that this problem is most prevalent with a heavier project. One that has 50+ tracks etc... and when some of these have many take lanes....not sure if that is the catalyst or not. In either case, this is surely a worrisome problem that should have been addressed by Cakewalk earlier on.
